Renthal Fatbar & Duo stem,any good,any reviews???

I was thinking of buying the Renthal Fatbar at 38mm rise,780mm width,(might cut down a bit?) and the Renthal Duo stem for my AM Nomad...I love the Alumigold color,kinda matches the fork stanchions.I seen this setup in a tutorial video being used by Fabien Barel...I know Renthal has been in the MX game forever and ive had good luck there,wondering about the MTB product?

I have the Duo stem and love it.
It is a bit of a pita, as it has a unique clamp system that makes bar swaps a bit more problematic. If you run one bar and set and forget, then no issues.

I was running a Point-One 50 mm stem, but prefer the Duo as it has a bit of rise that compensates for the lower rise of the Easton Havoc carbon bars I'm using with it. Fit, finish and weight are top of the line as well.
